What is Vector?
Vectors in Scala are indexed, immutable sequences. Think of them as similar to arrays, but with the key advantage of being immutable – meaning their contents cannot be changed after creation. This makes them very useful in concurrent programming and for data structures where you want to guarantee that data isn't accidentally modified. Vectors provide fast access to elements by index (like arrays), making them efficient for lookups and various data manipulations.
